本文研究新疆平原荒漠地区的伊犁绢蒿种子天然种衣 (也称膜 )的吸水速度、吸水量、失水性、种子脱膜方法、天然种衣对种子萌发的影响。结果表明这种天然种衣吸水速度高、吸水量大、失水时间长 ,有利于干旱条件下种子有效利用水分、促进萌发。 In this paper, the effects of natural watering rate, water absorption, water loss, seed release methods and natural seed coating on seed germination of natural silkworm seedpod (also known as membrane) in Xinjiang plain desert area were studied. The results showed that this kind of natural seed coat has the advantages of high water absorption speed, large water absorption capacity and long water loss time, which is favorable for the seed to effectively utilize the water and promote the germination under drought conditions.
